The PDF Info mapping (p-search-x-pdfinfo) collects metadata from
PDF documents. There are no options on mapping creation, but the
p-search-x-pdfinfo-executable variable can be used to configure the
location of your preferred pdfinfo command. The following
metadata fields are collected:
title
keywords
author
creation-date
modification-date
pdf-subject
pdf-creator
pdf-producer
pdf-pages
pdf-pagesize
